"In the case of hiding it how would you want to redisplay it after it has hidden the show hidden quests buttons, using the LBD etc?
Or would hiding the title and leaving the button showing work?"

Maintaining the LDB click to show hide but having another option to dont show the minion completely including the hide/show button and quest number tittle, when there isnt any quest tracked

so for example:

We have like 3 pvp quests we haven't made yet and we don't want tracked no other quest tracked aswell, Minion is turned on tho in the LDB but since we don't have anything tracked the button and title wont show. We accept a daily and then we get the minion showing the quest we just accepted the button and the tittle.

-an option to show the number of quests on the zone header would be nice.
This shouldn't be to hard to do, will add it to the todo list.

However I am a little unsure what you mean by:-will we get the ability to click on zone headers or quests to expand or hide details in the quest minion (similar to nQuestLog)

It is currently possible to collapse/expand zone headers by clicking them, though not possible to hide quest objectives with an alt-click on quests.
Also possible to show/hide quests in a zone by right-clicking the quest or the zone header and selecting from the minion.

Also by:-Only thing this don't have is the minimalistic quest details and lightheaded frame.
Do you mean the quest details frame that shows up when you click on a quest? (Where as in my case it displays the quest log)
Have an option coming to display only the quest half of the log when you click a friend to keep it smaller
Lightheaded I haven't had time to look at yet will one day ^_^

This is almost, imo, the best alternative to nQuestLog out there. Only thing this don't have is the minimalistic quest details and lightheaded frame.

I do have a question, will we get the ability to click on zone headers or quests to expand or hide details in the quest minion (similar to nQuestLog)?
I ask because there is auto zone expansion, but some times I like to look at a quest's details thats nearby for whatever reason.

And an option to show the number of quests on the zone header would be nice.

Sorry if you're not wanting to make this an alternative to nQuestLog, but like I mentioned, imo, it's the best quest log addon for me (sadly the changes to questlog has screwed it over)

The problem with the headers when all quests are untracker/invisible is still not resolved afterall. I think I know where the problem is on and I think its with the auto collapse/expand on enter/exiting a zone

IF you logout and in in same zone or a zone where you don't have quest it works fine but if u go into a zone where you have quests it shows all headers even those that are invisible.
